Retention of functionless pacemaker leads may occur following mechanical or infective problems (potentially or definitely infected) or after electrical failure of the lead. One hundred nineteen patients with a pacemaker lead (or leads) retained between 1970 and 1990 were reviewed retrospectively. Lead retention after an intervention dictated by potential or definite infection of the pacing system resulted in complications in 27 of 53 patients (51%), which in 22 patients (42%) were major (septicemia, superior vena cava syndrome, and further surgery under general anesthesia for recurrent "infective" problems) including three deaths. Complications were less likely if lead retention occurred after electrical failure with three minor and two major (surgery under general anesthesia, superior vena cava syndrome) complications in 66 patients (P less than 0.001). Bacteriology of swabs taken at the time of retention in the patients with potential or definite infection was unhelpful in predicting future complications: 8/18 patients (44%) whose swabs were negative had complications of which 5/18 (28%) were major. In our experience retention of functionless pacemaker leads after an intervention dictated by potential or definite infection of the pacing system, is associated with significant morbidity and mortality and should be avoided.

Seven pregnant women with symptomatic hydronephrosis had sonographically guided percutaneous nephrostomy for pyosepsis (five patients) or for pain with azotemia (two patients with renal transplants). Antibiotics had been ineffective in controlling pyosepsis in each patient; retrograde ureteral catheterization via cystoscopy was unsuccessful in one patient. After percutaneous nephrostomy, prompt clinical improvement was observed in all patients (i.e., sepsis was relieved and pain abated). Labor was not induced in any of the patients, and no adverse effects occurred to any fetus or mother. Eleven (eight percutaneous nephrostomy, three catheter exchanges) of the 12 procedures were done without conventional radiography and with sonographic guidance alone. After percutaneous nephrostomy, maneuvers to obtain a diagnosis and to treat the obstruction (if necessary) were delayed until after delivery. The causes of ureteral obstruction were calculi (four patients) and a gravid uterus (three patients). After delivery, stones were removed either percutaneously (one patient) or cystoscopically (two patients) or passed spontaneously (one patient); resolution of obstruction by the gravid uterus was proved by Whitaker test after delivery. Sonographically guided percutaneous nephrostomy is an effective and safe method to treat pregnant women who have symptomatic obstructive hydronephrosis associated with either pyosepsis or azotemia. The procedure is rapid, requires minimal anesthesia, has no radiation, and is safe for the fetus. The technique is a useful and perhaps preferable alternative to more invasive surgical therapy or retrograde stenting.

One way to nutritionally support patients who cannot swallow is to administer formula directly into the stomach. Placing a gastrostomy tube percutaneously using endoscopy avoids the risks of general anesthesia and wound healing that accompany surgical gastrostomy. Although certain conditions (eg, sepsis, coagulation disorder, portal hypertension) are contraindications to the procedure, it can be done in patients who have had previous abdominal surgery and in those with severe illness. A commercially available feeding formula is used. The type chosen and the frequency of administration are based on the patient's specific needs. With regular medical monitoring and daily care of the gastrostomy site, appropriately selected patients may be safely maintained with enteral feeding for months. An advantage of the percutaneously inserted tube is that it is easily removed when the patient regains the ability to eat, and the fistula heals rapidly.

Sinusitis is an important cause of sepsis in the critically ill patient and may be difficult to diagnose. Four patients admitted to the surgical intensive care unit with closed head trauma were found to have sinusitis as the cause of persistent bacteremia. All patients received pharmacologic doses of corticosteroids for treatment of head injury and had prolonged nasotracheal and/or nasogastric intubation. A bedside procedure was used for diagnosis and management. Under local anesthesia, a 16-gauge angiocatheter was inserted under the inferior turbinate and into the maxillary sinus. After purulent fluid was aspirated, the sinuses were irrigated with normal saline. All four patients defervesced within 24 to 48 hours of this procedure, and facial x rays demonstrated clearing of the maxillary sinus. It was concluded that: 1) Sinusitis is a complication of closed head trauma in critically ill patients and should be included in the differential diagnosis when persistent bacteremia occurs; 2) The use of corticosteroids in the treatment of head injury may increase the risk of sinus infection; 3) Facial x rays showing air-fluid levels and/or opacification are a valuable screening test for paranasal sinusitis; and 4) bedside aspiration of the maxillary sinus is an effective diagnostic and therapeutic technique for management of sinusitis in the critically ill.

In 1987, Yeager et al. reported that intraoperative epidural anesthesia with local anesthetics and postoperative epidural analgesia with opiates diminished postoperative morbidity. In our first clinical trial on this topic, the better postoperative analgesia with epidural bupivacaine-fentanyl failed to improve the outcome after major abdominal operations over that obtained with parenteral piritramide. This randomized controlled investigation was designed to assess whether intraoperative epidural anesthesia with bupivacaine plus light general anesthesia and postoperative epidural analgesia with morphine would diminish the overall rate of postoperative complications after major abdominal operations compared with general anesthesia (without epidural) followed by patient controlled analgesia with morphine, and with intraoperative epidural anesthesia with bupivacaine and light general anesthesia followed by postoperative bupivacaine-morphine analgesia. METHODS. A total of 292 patients undergoing infrarenal aortic bypass operation, gastric resection, gastrectomy, duodenum-preserving pancreatic resection, Whipple's operation or cystectomy and neobladder formation were randomly divided into three groups: 1. PCA group (patient controlled analgesia, n = 107): patients were operated on under general anesthesia (midazolam, fentanyl, N2O/O2, if necessary with addition of halothane, enflurane or isoflurane; muscle relaxation with pancuronium bromide). Postoperative management consisted in patient-controlled analgesia with morphine (Prominject), bolus 2 mg, lock-out 5 min (recovery room, intensive care unit) or 15 min (surgical ward). 2. EBM group (epidural bupivacaine+morphine, n = 95): operation under light general anesthesia (midazolam, low-dose fentanyl, N2O/O2, pancuronium bromide). In addition, a mixture of bupivacaine (0.25%) and morphine (60 micrograms/ml) was infused (approximately 0.1 ml/kg.h) via an epidural catheter during and after the operation (approximately 72 h). 3. EM group (epidural morphine, n = 90): operation under the same kind of general-epidural anesthesia as in the EBM group. Postoperatively, epidural injection of morphine (0.05 mg/kg in 10 ml of saline) on request up to the 3rd postoperative day. Quality of analgesia (at rest and when patients coughed vigorously), strength of cough, and rate-pressure product were recorded at 8:00 h, 12:00 noon, 16:00 h and 20:00 h on the 1st, 2nd and 3rd postoperative days. Incidence and intensity of all postoperative complications (cardiovascular, pulmonary, renal and other organ failure, reoperations, major infection, sepsis, thromboembolism, metabolic and mental disturbances) were assessed from the day of operation until discharge or death (n = 10), respectively. RESULTS AND DISCUSSION. In the PCA and EM groups analgesia was equal but of slightly inferior quality compared with the EBM group. The ability to cough was best in the EBM group and significantly worse in the PCA and EM groups, with no difference between the last two. (ABSTRACT TRUNCATED AT 400 WORDS)

The first Danish experience with Extracorporeal Shock Wave Lithotripsy (ESWL) using a second generation Lithotriptor (Siemens Lithostar) is reported. 306 patients underwent 392 treatments for 363 stones. There were 339 renal calculi including 5 staghorn calculi and 54 ureteral calculi. Treatments were performed under local analgesia (82%) or epidural or general anesthesia (18%) when invasive procedures had to be done in connection with the treatment. Stone fragmentation was achieved with 2487 +/- 1262 shocks. The first months stone clearance rate was 45%; 26% had fragments less than 6 mm; 29% had residual stones. Corresponding rates after 3 and 6 months were 58%, 24% and 18% and 70%, 21% and 9% respectively. Septicemia occurred in 4 patients and cardial arrhythmia in 34 patients (11%). No serious intra- or perirenal hematomas were registered. In 9% additional procedures were required and 11 patients had residual stones removed at open surgery. The used second generation lithotriptor with X-ray based stone localisation is effective for treatment of both renal calculi and ureteral calculi in situ in all three segments of the ureter.

This prospective study gives short-term results of 208 inguinal herniorrhaphy performed under local anaesthesia. The median age of the 201 patients (186 M, 15 F) was 57 years (17-87). Local anaesthesia could not be achieved in 1 (0.5%) patient because he was panic-stricken. No serious complications occurred. Peroperative systemic hypotension with bradycardia occurred in 6 (3%) cases. Two (1%) benign postoperative sepsis and 9 (4%) hematoma occurred. The median postoperative hospital stay was 2.8 days (1-10). Twenty seven (13%) patients were discharged on the first postoperative day, 93 (46%) in a period of time less than or equal to 2 days, 147 (73%) in a period less than or equal to 3 days and 184 (91%) in a period less than or equal to 4 days.

In this commentary, the impact of the introduction of manual vacuum aspiration (MVA) for incomplete abortion patients and for early uterine evacuation is discussed for the University Teaching Hospital in Lusaka, Zambia. This 3-year training and service delivery program was begun in 1988 after it was clear that 15% of maternal deaths were due to illegally induced abortion. The prior procedure of dilation and curettage (D and C) required use of the main operating room and general anesthesia, which resulted in severe congestion and treatment delays. As a result of the new MVA procedure, congestion has decreased substantially, treatment is safer and more timely, and the staff's ability to provide abortions has increased. Family planning counseling is provided to postabortion patients in a more thorough fashion, and the savings in time has improved the quality of patient-staff interactions. Specifically, the patient flow has improved from a 12-hour wait to a 4-6 hour wait and rarely requires overnight hospitalization. The demand for the main operating room had decreased which frees space, time, and commodities for other gynecological treatment. The shorter procedure and release time means a minimal loss of earnings and productivity, and allows for greater privacy in explaining absences to families, schools, or employers. The improved quality of are is reflected in the figures for number treated, i.e., in 1989, 74% were treated with MVA for incomplete abortion 12 weeks and pregnancy termination 8 weeks compared with 26% treated with D and C. In 1990, the figures were 86% with MVA and 14% with D and C. The likelihood of complications from hemorrhage and sepsis have also been reduced. The MVA procedure is also less traumatic for the patient. The increased access to safe legal abortion services is reflected in the ratio of induced to incomplete abortions between 1988-1990 (1:25 to 1:5). Family planning counseling is provided by a full-time counselor who counsels preabortion and postabortion and schedules 2-week follow-up appointment. These achievements have been made in spite of a declining economy and difficulties in the health sector. Unfortunately, conditions throughout Zambia are such that access to safe abortion is restricted. Effort is underway to expand this MVA training and service delivery in provincial hospitals and to conduct research on other effective strategies to reduced unsafe abortion and improve family planning care.

Sternal sepsis following median sternotomy is an infrequent yet devastating complication of cardiac surgery, leading to prolonged hospitalization, increased hospital expense, and a high associated morbidity and mortality. The development of sternotomy infection is multifactorial. Numerous prospective and retrospective studies have pointed to a multitude of clinical and perioperative variables as being causative, with as many other studies presenting evidence of the contrary. This has led to confusion about which clinical variables should be modified so as to minimize the individual patient's risk for developing this severe complication. Other less obvious factors also come into play. Malnutrition, whether overt or subclinical, is not uncommon in cardiac patients. Immune competency is affected by operative trauma, as well as a variety of perioperative factors including underlying nutritional status, transfusion, cardiopulmonary bypass, and anesthesia. This creates a complex milieu for the development of postoperative infection. In this review, the multiple risk factors of median sternotomy infection are studied and treatment options briefly discussed.

There has been significant decrease in maternal morbidity and mortality of sickle cell disease patients during pregnancy due to better understanding of the pathophysiology of the disease and physiologic changes during pregnancy. Prophylactic blood transfusion does not appear to reduce complications in patients with sickle cell anemia. Patients with sickle hemoglobin C disease and with S beta thalassemia+ have fewer complications but still need close monitoring. Blood transfusion therapy should be made available for medical and obstetrical complications to include increasing hypoxemia, progressive anemia, acute chest syndrome, twin pregnancy, splenic sequestration syndrome, preeclampsia, septicemia, or prior to general anesthesia and surgery. Blood transfusion therapy is associated with hepatitis, allergic reaction, alloimmunization, AIDS, and iron overload states. These aspects should be considered prior to using blood transfusion therapy. Excellent prenatal monitoring and aggressive intervention should be instituted when problems arise for the successful management of the pregnant patient with sickle cell disease. Prenatal diagnosis and cord blood screening should be made available for the infant. Appropriate pediatric referral and prophylactic penicillin is recommended for the infant with sickle cell disease.
